HL7
HL7 (Health Level Seven) is a standard way for healthcare systems to share patient information between different computer systems in hospitals, clinics, and other healthcare facilities. Think of it as a common language that allows different healthcare software systems to talk to each other. For example, when a doctor's office needs to send patient records to a hospital, or when lab results need to be automatically added to a patient's electronic health record, HL7 makes this possible. It's like a translator that helps all the different healthcare computer systems understand each other.
